12.4.29

विकार: ख्यायमानोऽपि प्रत्यगात्मानमन्तरा । न निरूप्योऽस्त्यणुरपि स्याच्चेच्चित्सम आत्मवत् ॥ २९ ॥

vikāraḥ khyāyamāno ’pi pratyag-ātmānam antarā na nirūpyo ’sty aṇur api syāc cec cit-sama ātma-vat

vikāraḥ
the transformation of created existence
khyāyamānaḥ
appearing
api
although
pratyak-ātmānam
the Supreme Soul
antarā
without
na
not
nirūpyaḥ
conceivable
asti
is
aṇuḥ
a single atom
api
even
syāt
it is so
cet
if
cit-samaḥ
equally spirit
ātma-vat
remaining as it is, without change

Although perceived, the transformation of even a single atom of material nature has no ultimate definition without reference to the Supreme Soul. To be accepted as factually existing, something must possess the same quality as pure spirit — eternal, unchanging existence.
